ClassNotFoundException with Ant and JUnit - ant

Question

Here is my code:
<project name="SampleProject" default="test-html" basedir=".">
<property name="ws.home" value="${basedir}" />
<property name="ws.jars" value="E:/jars" />
<property name="classes" value="${ws.home}/build" />
<property name="test.src" value="${ws.home}/src" />
<property name="test.reportsDir" value="c:/report" />
<!-- classpath -->
<path id="test.classpath">
<fileset dir="${ws.jars}" includes="*.jar" />
</path>
<!-- clean -->
<target name="clean" description="clean up">
<delete dir="${classes}" />
<echo message="Directory deleted..." />
</target>
<!-- create -->
<target name="create" description="create">
<mkdir dir="${classes}" />
<echo message="Directory created..." />
</target>
<!-- compile -->
<target name="compile" depends="clean,create">

<echo message="compilation completed..." />
</target>

<fileset dir="${test.reportsDir}">
<include name="TEST-*.xml" />
</fileset>
<report todir="${test.reportsDir}" />
</junitreport>
</target>
</project>
I am getting following problem in report generated with command prompt:

I tried a lot to get out from here, but I didn't get solution. Help me.

Answer 1

It looks like the classes you compile are not on your test classpath.
The javac compiles to ${classes}, but that dir is not included in your definition of test.classpath.
Try adding the dir as a pathelement:
<path id="test.classpath">
<fileset dir="${ws.jars}" includes="*.jar" />
<pathelement path="${classes}" />
</path>
